Formula Widget for Tank Gauges
Hello,
Is there a way to run an analysis on a group of devices that contain certain tags, and then take that data and show the result on a display widget?
More specifically; I have multiple tank monitors measuring water levels that send in data once an hour. I would like to take the last data point and subtract it from the first data point within a 24hr period (12pm datapoint- 12am datapoint) to get the total increase of water that day for each tank monitor with the specific tags. I would then want to take the values from each tank and add them together to get the total accumulation of water entered into all of my tanks that day.
Thanks,
Chris
